STRING protein interaction network
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

argRArac family transcriptional regulator, l-arginine-responsive activator; ArgR could be a transcriptional activator of the dauBAR operon in response to the presence of L-Arg (329 aa)    
Predicted Functional Partners:
Octopine transport system permease protein OccM; HEQRo_perm_3TM: amino ABC transporter, permease , 3-TM region, His/Glu/Gln/Arg/opine family domain protein
Histidine transport system permease protein HisQ; HEQRo_perm_3TM: amino ABC transporter, permease , 3-TM region, His/Glu/Gln/Arg/opine family domain protein
Arginine/ornithine transport system atp-binding protein; Part of the arginine-inducible binding-protein-dependent transport system for arginine and ornithine. Probably responsible for energy coupling to the transport system
annotation not available
Arginine/ornithine succinyltransferase, alpha subunit; Catalyzes the transfer of succinyl-CoA to arginine to produce N(2)-succinylarginine. Also acts on L-ornithine
Arginine/ornithine succinyltransferase aii subunit; arg_catab_AstA: arginine N-succinyltransferase
Bifunctional n-succinyldiaminopimelate-aminotransferase/acetylornithine transaminase protein; Transaminates both N(2)-acetylornithine and N(2)- succinylornithine
Ornithine carbamoyltransferase; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline, which is a substrate for argininosuccinate synthetase (ArgG) involved in the final step in arginine biosynthesis
Ornithine carbamoyltransferase; Involved in the catabolism of arginine. Catalyzes the phosphorolysis of citrulline, the reverse reaction of the biosynthetic one, yielding ornithine and carbamoyl phosphate which serve to generate ATP from ADP . This catabolic OTCase does not carry out the biosynthetic reaction because of a poor affinity and a marked cooperativity for carbamoyl phosphate
Arginine/ornithine transport system substrate-binding protein; Belongs to the bacterial solute-binding protein 3 family
